nope. try running this script to see
what's going on:
...
class Foo:
print "this is executed when the class statement is executed"
def __init__(self):
print "this is executed when a new instance is created"
foo = Foo()
...
next, try removing the "foo = Foo()" line
and run it again.
finally, try adding multiple copies of
"foo = Foo()" and run it.
get it?
